Behind the scenes

Snakeweed (Polygonum bistorta) is one of the forty members of the Polygonum genus, like knotgrass. Because knotgrass may refer to several species of Polygonum, the two are easily confused. Snakeweed, commonly known as Bistort, was used traditionally to treat ulcerative sores and stomach ailments and was also an ingredient in a springtime pudding in Northern England.[3]
